    Any recommendations on where I can find the proper sized prop puller to remove the props on our 320 v drive?

    Dean,



    The prop scan shop I'm using lands prop pullers which work just fine. I didn't have an issue taking props off my 320. If your intention is to bring the props to a shop, ask and maybe they'll offer the same service. You would give them CC to secure the unit and they would charge it in case you don't return the puller. But, when you bring the props and the puller back, the puller ends up a free tool for you to use.

    I bought a 9inch pulley puller from autozone. It worked well, I left the Nut on to protect the threads on the shaft from being damaged. However, for the first time, I was pretty shocked with how violent the props came off the shaft. My props were off last winter so it may have made it a little easier.

    I keep the one I made right on the boat, along with the spare props, so it's always there when I need it. Also, there is no way in hell I would EVER use a prop knocker on my boat - the impact from using this device is transferred through the shaft to the transmission thrust bearing, which is a tapered roller bearing just behind the output flange. Take the time to find the right puller, and use it.

    So a friend gave me a hand with removing the props this weekend now my next question is regarding balancing, repair and reconditioning. Is Pro Scan the way to go for this service? Seems like there is only one shop listed in CT. Also what should I expect as far as cost? Also is it a good time to address the shaft bearings? It seems I may have about 2 seasons left on them.

    So now I'm ready to put the props back on this weekend. Is there anything of note I should be doing to prep the shafts? A friend of mine said he uses a seating compound of some sort to ensure props are perfectly mated to the shaft?

    Dean,

    Your friend is likely referring to lapping compound. In order to achieve the best fit between the shaft and prop, it is common to lap the prop to the shaft. I have a blog entry concerning flange lapping, but the process is the same for the props. See here for that page:

    http://searay340restoration.blogspot.com/2011/02/prop-shafts-and-flanges.html

    There are also several online videos you can reference - just do a search for propeller lapping. Once you're done with the lapping procedure, you thoroughly clean the shaft and prop, and then perform the final installation as normal.
